In this mode, pacing and sensing functions are off.  The OFF 
mode is used to determine and evaluate the morphology of an 
intrinsic rhythm.  With external pulse control, the OFF mode is 
used for electrophysiological studies.  The OFF mode can be 
programmed temporarily. 

OFF Mode – The OFF mode can be transmitted as a 
temporary program only to permit evaluation of the patient’s 
spontaneous rhythm.  (see Section 2.1.11). 

 

For the Stratos CRT-Ps, there are 2 possible settings for the BiV 
Sync parameter: OFF and BiV RV RV-T. 

OFF - If the BiV sync parameter is set to OFF, the CRT-P 
ignores the left-ventricular channel and functions like a 
conventional dual-chamber pacemaker.  Consequently, pacing is 
not delivered into the left ventricle.   

BiV RV RV-T - When set to "BiV RV RV-T" the device provides 
biventricular pacing with sensing in the right ventricle and 
triggering of a right ventricular sensing event in the left ventricle. 

The biventricular synch settings can be activated together with 
the DDD(R), DDI(R), VDD(R), and VVI(R) pacing modes. 

 

Sensing – The Stratos CRT-Ps do not sense in the left 
ventricle. 
AV Conduction – In patients with intact AV conduction, the 
intrinsic atrial tachycardia is conducted to the ventricle 1:1.  
With the resynchronization mode activated, spontaneous rate 
of the right ventricle mode is synchronized for a rate up to 
200 ppm in the left ventricle.  For this reason, biventricular 
pacing mode should be turned OFF in such cases.
